Highly stereoselective Ru(II)-Pheox catalyzed asymmetric cyclopropanation of terminal olefins with succinimidyl diazoacetate

The Ru(II)-Pheox complex is an efficient catalyst for the intermolecular cyclopropanation of various terminal olefins with succinimidyl diazoacetate. This catalytic system can perform under mild conditions, and the desired cyclopropane products are obtained in high yields with excellent diastereoselectivity and enantioselectivity.
